How to merge multiple dicts with same key?

This library helped me, I had a dict list of nested keys with the same name but with different values, every other solution kept overriding those nested keys.

from deepmerge import always_merger

def process_parms(args):
    temp_list = []
    for x in args:
        with open(x, 'r') as stream:
            temp_list.append(yaml.safe_load(stream))

    return always_merger.merge(*temp_list)
